IMPROVEMENT ,IN BAG-FASTENERS.

Specification forming part of Letters Patent No. l90,666, dated May 15,1877 application filed April 20, 1877.

for fastening bags; and the invention consists in the specialarrangement and constructionof parts hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction andoperation, reference being bad to the accompanyingdrawing, and

to the letters of reference marked thereon, in

which- Figure l is a plan or external view; Fig. 2, a view with one ofthe sides of the casing removed, showing the internal arrangement ofparts; Fig. 3, a transverse section on the line a; :0, Fig. 1; and Fig.4, a longitudinal section, the fastening being open.

A represents the casing, within which is arranged the mechanism forholding the cord. This casing may be made of any desired form 5 but Iprefer and have adopted the one shown in Fig. 1 of drawing as answeringthe purpose of a handle and a flat surface, to which a cord can beattached.

The casing A may be cast or otherwise constructed, as desired. I preferto have it stamped from sheet metal, in two longitudinal duplicatesections, at, having a flange, o,

1 extending around the outer edge of each, ex-

cept at 02 and la,- on the opposite edges of the central part of thecasing, where the cord D passes through.

The sections are held together by six or more rivets, e e e e, d, and f.The rivet d is placed in the center of the opening 2', and serves as thepivotal point for two curved arms, B B, each one of which is providedwith one or more shoulders, h, so placed as to be equidistant from therivets e 6.

Two or more of the rivets e are placed on each side of and in a lineparallel to the arms B B when extended, and serve as the surfacesagainst which the cord D is jammed by the arms B B. These arms arespread or forced apart by the slotted wedge O, which has lateral playupon the rivet f. The wedge- O is provided with a thumb-piece, g. Thewedge O is of less breadth at its juncture with the thumb-piece than ata short distance from it, the side lines forming a curve in harmony withthe curvature of the arms BB. This causes the arms to close upon thewedge, and retain it in place until sufficient force is applied to drawit out.

The operation of this device is as follows: The bag-fastening beingopen, as shown in Fig. 4 of the drawing, the cord D is passed "throughthe opening it, between one of the arms B and rivets e e, and out atopening a; thence through the eyelet-holes of a bag, and back throughthe opening 23, and between the other arm B and rivets e e, and out atopening 70. Both ends of the cord are then taken in one hand, and thefastening in the other, and drawn up as close to the bag as it can begotten. The wedge is then forced in tightly, jamming the cord betweenthe shoulders h and rivets e. The arms B B close in under thethumb-piece sufficiently to prevent the wedge from being withdrawn byany ordinary circumstances, yet permit its withdrawal at will.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

The combination of the casing A, rivets e, pivoted arms B B, havingshoulders d, and wedge O, substantially as shown and described.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
